In this paper, we study some equivalence relations between

continuous frames in a Hilbert space H. In particular, we seek two necessary and sufficient conditions under which two continuous frames arenear. Moreover, ...

Thresholding and compressed sensing in combination with both wavelet and

shearlet transforms have been very successful in inpainting tasks. Recent results have

demonstrated that shearlets outperform wavelets ...

This paper is devoted to definition standard higher dimension

shearlet group $ \\mathbb{S} = \\mathbb{R}^{+} \\times \\mathbb{R}^{n-1} \\times\\mathbb{R}^{n} $

and determination of square-

integrable ...

In this paper, the shearlet theory is extended from ordinary matrices to block matrices and its properties are investigated. More precisely, the block shearlet group is defined as a semidirect product group and the block ...

از روش‌های معمول در بهره‌برداری از نظام‌مندی‌ها و ویژگی‌های هندسی در سیگنال‌های چندبعدی می‌توان به استفاده از اتساع ناهمسانگرد و مقیاس‌بندی سهموی اشاره کرد که اساس تبدیلاتی همانند قیچک و پیچک را شکل می‌دهند. در چنین ...
